. That is tough to answer, in terms of replacing the stock sub using the stock free-air configuration the pioneer is a very good match. Pioneer's subs that are designed to be used in free air application historically have performed very well. I will not go into to great detail but if a woofer is to be used in a free-air environment it needs to possess specific characteristics and pioneer's engineers have done a very good job of developing a speaker that can meet those parameters. If you are looking into employing a enclosed subwoofer, the sky is the limit. I had a JL 12W7 in my SC400 and it was CRAZY!!! It was a bass machine, it was very accurate and at the same time was very loud. I was not not concerned about weight so the heavy subwoofer and heavy box did not bother me. Oh also it significantly reduced my trunk space. With my IS-F, I do not want to add weight but at the same time want to maximize the stock stereos potential so I am going to add the Pioneer and see how I like it. I am a moderate audiophile, my home audio equipment includes B&W and Vandersteen transducers, and old school Carver and Denon components. It really depends on your music taste on what type of sub-woofer, type and size of amp and type of box I would consider purchasing and installing.

Sorry I had Steve Meade's screen name WAY off. It is meade916, He is the true expert when it comes to car audio he does some of the most amazing installs. You may want to shoot him a PM.

I have a non ML system and it bumps pretty good all the way to 60.... But I am use to more base.. My Outland Sport has the 710 watt rockford system.. Id say the lexus has a crisper sound but i want just a bit more base.
apparently, dynamat aint enough!

Here you go. Guy says he will custom cut them for your use. I wonder if he will also use thinner stock, meaning if 3/4" stands it away too far for the cover to fit on it, will he use 1/2 or 1/4" MDF? Also would tell him it is for a down firing sub to see if that makes a difference with the clearance there..

I did not realize that the ML amp was rated at 8 ohms. This speaker is a 4 ohm speaker.. The amp will be pushing out more current and could get rather warm, possibly hitting it's thermal protection and shutting itself off. Most high end amplifiers will do ok for a while pushing out to a 4 ohm speaker, but there really isn't a way to know how "high end" the ML amp is. Is the sub in a ML system driven off of its own amplifier? Are there a few different amps in there? I think I saw the ML amp is fan cooled as well. If you are listening to the music at a reasonable volume then there shouldn't be too much of a problem. If you crank it up because Beyonce is singing "Single Ladies" (and really, who doesn't?
) It probably won't do much harm. If you crank to volume to max and play the entire collection of Tupac, that probably would stress it to the point of thermal shutdown. I've never heard or seen a ML system in person, so my knowledge is limited on what it looks like and is capable of.
